I recently knocked my laptop off a table. The fall cracked the LCD screen but the laptop appeared to be okay otherwise. I plugged a monitor into the laptop's AGP port, and was able to use the laptop without any apparent problems. So I replaced the LCD screen. Now the laptop will not boot. After I finished the replacement, the system booted once to the screen that gives a user the option of going into the BIOS and then it went black. However, the "on" light remained lit and would not shut off when I pushed and held down the power button. The only way to cause the light to go out is to disconnect the battery. On a couple of subsequent attempts to power up the laptop, I have heard the HDD start to spin up, and the indicator lights flashed, indicating that the system was powering up. But then everything stopped. And now, the most that happens when I press the power button is that the lights flash. But I do not hear the HDD spinning up. According to the indicator light, the battery is fully charged. Any ideas? Huh?

You replaced the LCD yourself? Have you done this before? Laptops are pretty tricky to replace hardware. You might have disconnected something by mistake. There might be a short somewhere.

Yes. I replaced the screen myself. I have many years of experience building PCs and doing repairs and upgrades. This was the first time I have replaced the LCD screen in a laptop. But I downloaded a guide, and it it wasn't a difficult job. So I may well have done something wrong. But I don't know what it could be. Further, I note that the laptop did boot at least as far as the menu screen I referred to in my first post. Huh?

Are you sure the screen you used is totally compatible with the laptop.

The data and power cable interfaces match up. And the screen did display an image for a few seconds. Other than that, I don't know how I can be sure. I suppose I could take the screen out and get a number to track down. And unless I hear a likely solution otherwise, that may be my next step. Huh?

Well, I guess I would have thought you had some assurances before buying the screen.

Assurances? If you mean a warranty, then, yes, it came with a warranty. And if it's the wrong screen, I can exchange it. Which is the way the parts-ordering process works with any part, as far as I know. Beyond that, I do not know much about laptop LCD screens specifically, but if the data cable and power cable interfaces fit, isn't that a pretty good indicator that it is the right screen? Or are there differences between different models with the same interfaces that would cause serious problems? I can see how that could be a nightmare. Huh?
